Specification of Letters Patent.

T0 all whom it may concern:

Be it known that I, ARTEMUs N. HADLEY, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented certain new and useful Improvements in Portable Field-Derricks, of which the following is a specification.

The object of my inventionlis to produce a cheap, yet efficient deviceby means of which shocks of corn, other crops or material may be easilylifted from the ground to a vehicle, or'vice versa, the arrangementbeing such that while the loaded vehicle is driven to a distant point todischarge its load, the'apparatus may be left in the field and attachedto another vehicle and used for loading the same, the arrangement alsobeing such that the apparatus may be easily transported from place toplace by the vehicle to which it is attached.

Figure 1 is a perspective view of one form of my apparatus. Fig. 2 is aside elevation of the vehicle and the platform which supports thederrick. Fig. 3 is a detail vertical section of the support for thelower end of the mast. Fig.` 4 is a similar detail of the intermediatesupport by means of which the vertical position of the mast may beadjusted. Fig. 5 is a plan of the parts shown in Fig. 4 in one positionof adjustment; Fig. 6 a similar view of the parts shown in Fig. 4 inanother position of adjustment; and Fig. 7 a perspectlve detail.

In the drawings, 10 indicates a suitable derrick mast to which issecured near its upper end `a tee-fitting 11 through the transverseportion of which is passed a cross-arm 12 said cross-arm beingadjustable transversely through the fitting and held in any desiredposition by a suitable bolt 13. Arm 12 also passes through a fitting 14which is carried at the upper end of diagonal bar 15 the lower end ofwhich is stepped in a tting 16 secured to the mast 10.' Mounted upon oneend of the cross-arm 12 is a suitable carriage 17 which is adapted to berolled upon the cross-arm. Secured to the outer end of cross-arm 12 isone end of a cable 18 which passes from thence over a suitable guide orpulleycarried by carriage 17 thence down through block 19 thence up overa second suitable guide carried by carriage 17, from thence to a block20 attached to the opposite end of arm 12, from thence downward over asuitable pulley 21 into the interior of mast 10 and thence downward andout at the lower end of mast 10 around a suitable pulley 22 mounted in astep-bearing 23 the cable being thence passed preferably to the rear sothat a horse or other draft device may be attached thereto. Mast 10 isstepped within the casing 23 and is both rotatable and axially movabletherein, a suitable foot-lever 24 engaging the lower end of mast 10 fora purpose which will appear. Resting upon the upper roughened end 25 ofthe casing 23 is a rotatable collar 26 carrying a cam-shaped annularflange 27 which surrounds mast 10. Resting upon the upper roughened end28 of' collar 26 is a second collar 29 which is similarly cani-shaped tocorrespond with the flange 27. Secured to mast 10 is a fitting 30 whichcarries a horizontal roller 31 adapted to rest upon flange 27 and collar29 and thus support the weight of the mast 10 and its attached parts.Step-bearing 23 is mounted upon a suitable platform 32 which is adaptedto lie transversely beneath the vehicle 33 and erected from saidplatform 32 is a suitable tripod 34 which carries a ring 35 throughwhich mast 10 passes. Rotatably mounted within ring 35 is a crescent 36which embraces mast 10 and rotatably mounted in crescent 36 is a secondcrescent 37 through which mast 10 also passes. Crescent 36 may be heldin any angular position by a suitable latch 38 which may be thrown intoany one of the notches 39 formed in ring 35, and crescent 37 may besimilarly held in angular adjustment by means of a latch 40.

As previously stated, platform 32 is adapted to extend transverselybeneath the vehicle 23 the arrangement being such that the wheels of thevehicle may pass over the platform when desired. In order to hold theplatform and prevent the same from tipping while the vehicle is beingloaded, I provide suitable bars 41 each of which is supported upon theplatform by means of parallel links 42 and these bars 41 may be thrownup into engagement with the vehicle, as for instance, the axles or hubs,by means of brace bars 43 the lower end of each of which may take into asuitable ratchet 44 carried by the platform 32. In order to transfer themechanism easily, suitable chains 45 are attached to the latform 32 andare arranged to be inclined forward and attached to suitable eyes 46secured to the bed of the wagon 33 the arrangement being such that whenthe wagon is started forward 'the chains 45 will have a tendency to liftthe platform 32 slightly from the ground and drag it along beneath thewagon. Suitable runners 32 are placed beneath the platform 32.

In order to enable the operator to intelligently use the adjustingcrescents 36 and 37 in bringing the mast 1() to its proper substantiallyvertical position, I 1provide a plumbing ring 47 which is slightly argerthan mast 10 and embraces the same, and is suspended in position bythree chains which are attached to mast 10 near its upper end.

In operation, Wagon 33 is driven over platform 32 until it liestransversely beneath the wagon between the wheels. The chains 45 arethen attached to eyes 46 said chains being of such length that, when theWagon starts forward the platform will not lag far enough behind to becaught by the rear wheels. The bars 4l are then dropped and theapparatus is driven into the field. When it has arrived at a point nearthe shock to be lifted, bars 41 are thrown up into engagement withadjacent points of the wagon, and crescents 36 and 37 are adjusted untilmast 10 stands substantially plumb as indicated by plumbing-ring 47.Collar 26 and ring 29 are then adjusted upon the upper end of thecasting 23 until the highest point thereof will lie in such positionthat roller 31 will be upon that point when the mast is swung so as tobring the lifting end of cross-beam 12 into position adjacent the shocklto be lifted. The shock is then attached to block 19 and lifted by aproper pull .upon cable 18. As soon as this is done a slight pull orshove upon the shock turns mast 10 and pulley 31 rides down an inclineformed by iiange .27 and collar 29 into the crotch, the swing of themast 10 being accomplished by the weight of the shock and the swingbeing sufficient to throw the shock around over the wagon-bed upon whichit may be readily deposited. The foot-lever 24 is convenient for liftingmast 10 in order that ring 26 and collar 29 may be readily adjusted. Theapparatus may be moved from place to place until a load is obtainedwhereupon chains 45 may be disconnected and the loaded wagon driven awayfrom the platform and while it is being driven to a point at which theload is to be discharged, another wagon'may be driven into position overthe platform and the operation repeated. By this means a single loadingapparatus may be used with a number of wagons in succession.

It will be readily understood that the form of platform 32 and thedetails of construction of the mast and lifting apparatus may be variedwithout departing from the broad spirit of my invention.

I claim as my invention.

1. In a loading apparatus, the combination with a mast and liftingapparatus carried thereby, f a self-supporting support for said mastadapted to project beneath a vehicle and over which the vehicle may run,and means for detachably connecting said sup- Y port to the vehiclewhereby it may be transported. g

2. In a loading apparatus, the combination with a support adapted toextend beneath a wagon and rest upon the ground, of a mast supported onsaid support, lifting apparatus carried by said mast, and means carriedby the support for engagement with the wagon, whereby the weight of thewagon may be applied to the support to prevent the same from tipping.

3. In a loading apparatus7 the combination with a suitable supportadapted to extend beneath a wagon, of a mast carried thereby, a liftingapparatus carried by said mast, and braces carried by the support, and

means for throwing said braces upward into engagement with the wagon,for the purpose set forth.

6. In a loading apparatus, the combination with a suitable support and asubstantially vertical mast mounted thereon, and capable of both angularand axial' movement thereon, means for normally producing axial movementof the mast upon rotary movement thereof, and other means forengagingthe mast and preventing axial movement thereof.

7. In a loading' apparatus, the combination with a suitable support anda substantially vertical mast rotatably mounted thereon, of means foradjusting the vertical angle of said mast, and an annulus surroundingsaid mast and loosely suspended from an upper portion of the mast,whereby it will serve ARTEMUS N.
